针对这种情况，采用伽马反演，来排除因泥质含量增加形成的低速异常现象，再结合速度反演，较准确地预测出了双家坝地区飞仙关组鲕滩的发育情况，落实了其分布范围，为下一步勘探提供了可靠的资料。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。

According to the distribution law of three zones in uncovering coal and the relation between the distribution law and delay outburst, the prevention and control technology is brought up, which firstly adopts gas drainage in the coal through drainage hole to release the outburst power by stages, and then intensifies the intensity of uncovering coal and increases the length of stress relaxation zone and stress concentration zone by using the liquid injecting and freezing to prevent the coal rheology. At last, the shoring measures to prevent roof falling is tabled.
